I guess I stumped everyone. :(

For a beginner (someday I'll stop being a beginner), that's where the  
problem starts. I have this message called preOpenStack, which I can  
use to set up my stack, and it's handled in the script for the . . .  
card? Yes, I see why; but it is not intuitive.

Thanks for your very lucid explanation of "owner" and "target" and  
"me". It turns out that my problem was this: during development I  
have an "initialize" button on the one card of my main stack (so as  
to set up or reset the underlying database), and the button's script  
says
		send "preOpenStack" to this stack
If my preOpenStack handler begins with "if the owner of the target is  
me" then I get an execution error (because of passing that message  
into the stratosphere) when I press the "initialize" button; but it  
works fine when I'm really opening the stack. Alternatively, the line  
"if the target is me" works with the button, but does nothing if I'm  
really opening the stack. All that makes sense I think. I can't think  
how to write that line for both contexts -- suggestions?
